Step-by-step explanation:
Gout is a condition where uric acid crystals accumulate in the joints, causing pain. Increasing fluid intake is important when on treatment for gout because it helps to flush out uric acid from the body through urine. Drinking enough water, around 2 to 2.5 liters per day, can help prevent the formation of kidney stones and reduce the risk of gout. Additionally, following a diet low in protein, nitrogen, and sodium, and avoiding purine-rich foods like tea, coffee, and chocolate can also be beneficial for managing gout.
